[Industrial applications]

 The present invention is a lighting fixture equipped with a gas cleaning device, and more specifically, it is more stable than before by positively and efficiently utilizing electric wind and electrostatic attraction, which are electrochemical phenomena. The present invention relates to a lighting fixture equipped with a gas cleaning device that can not only improve the dust collection efficiency by the above operation, but also extremely quietly and extremely improve the deodorizing efficiency.

[0002]

[Prior art]

 Conventionally, as this type of gas cleaning apparatus, for example, there is one disclosed in Japanese Patent Laid-Open No. 63-59963.

That is, as shown in FIG. 3, the gas cleaning apparatus disclosed in the above publication has a pair of positive and negative ionization electrodes 16 and a ground 17, and the negative electrode 16 a of the ionization electrode 16 is a platinum-impregnated honeycomb-shaped structure. In addition to using ceramics, a comb-shaped electrode is used for the positive electrode 16b.

In the gas cleaning apparatus 18 having the above structure, when a direct high voltage 19 is applied to the pair of positive and negative ionization electrodes 16, a corona discharge is generated between the pair of positive and negative ionization electrodes 16, and the ionization electrodes 16 are The gas in the vicinity will be ionized.

Further, the gas ionized as described above moves (arrow B) as an ion flow toward the negative electrode 16a, and gas convection is induced via the ion flow, and the negative electrode 16a The gas flow passes through the inside of the negative electrode, and fine particles such as fine dust and odor contained in the gas flow are charged by the electric field of the positive electrode 16b to the positive electrode, and the negative electrode is charged. It will be adsorbed to the negative electrode 16a by the negative electric force of 16a.

Therefore, the gas containing fine particles such as fine dust and odor is filtered and discharged (arrow C) while passing through the negative electrode 16a by the above series of repetitions, thereby being cleaned. It will be.

[0007]

[Problems to be solved by the device]

 However, the gas purifier having the above structure has the following problems.

That is, the ionization electrode 16 of the gas cleaning apparatus having the above-mentioned configuration applies a negative voltage to a so-called dust collecting electrode for adsorbing fine dust, odor and other fine particles in the gas, In addition, a positive voltage is applied to the electrodes for corona discharge for generating electric wind.

Therefore, a large amount of secondary electrons are emitted due to collision of ion particles, electrons, and the like with a positive electrode for discharge having a high current density, and a so-called avalanche phenomenon is likely to occur.

Therefore, not only the corona discharge generated between the pair of positive and negative ionization electrodes 16 becomes unstable, but also spark discharge easily occurs, and the electric field strength of each electrode unit for improving the dust collection efficiency is increased. Not only is it difficult to increase the strength of the dust collection, but some of the fine particles that have been affected by electron flow etc. are difficult to be adsorbed because the dust collection electrode is applied to a negative voltage. The dust collection efficiency of will also decrease.

Therefore, in order to improve the dust collection efficiency of the fine particles in the gas, it is necessary to reduce the size of the through hole 20 such as the honeycomb portion through which the gas flow of the dust collecting electrode passes. However, due to various electrical and structural restrictions, it was difficult to maintain a highly stable and highly efficient dust collection operation.

Further, in the gas cleaning apparatus having the above-mentioned configuration, a large amount of secondary electrons are emitted due to collision of ion particles, electrons, etc., with a positive electrode for discharge having high current density, which is a so-called electron avalanche phenomenon. And the corona discharge generated between the pair of positive and negative ionization electrodes 11 becomes unstable, and spark discharge easily occurs.

Therefore, the noise of the spark discharge generated via the corona discharge generated between the pair of positive and negative ionization electrodes 16 becomes unpleasant, and even if the gas purifier is downsized, its place of use must be considered. However, there was a problem that could be called a fatal injury even in actual use.

However, the present invention solves all the above problems, and it is highly stable and does not cause electron avalanche phenomenon at all, and the structure of the electrode for collecting dust is not restricted by a particular restriction. Not only will it be possible to maintain a highly efficient dust collection operation and to maintain the quietness during gas cleaning, but a wider range of gas can be provided, for example, by providing at least one lighting fixture installed in each room. It is an object of the present invention to provide a luminaire equipped with an extremely excellent gas cleaning device that can perform cleaning closely.

[0015]

[Means for Solving the Problems]

 That is, the present invention is that the lighting apparatus main body 10a is provided with the gas cleaning device 1 in a lighting apparatus mounted on a ceiling, a wall, or the like.

Further, the gas cleaning apparatus 1 has a needle-shaped electrode 2 and at least one through hole 6 facing the needle-shaped electrode 2 and extending along the tip direction of the needle-shaped electrode 2. A positive electrode portion 4 provided with a dust collecting electrode 3, the needle electrode 2 being negatively applied, and the dust collecting electrode body 3a being positively applied; And the dust collecting electrode main body 3a is detachably attached to the gas cleaning device 1.

[0017]

[Action]

 In the luminaire having the gas cleaning device having the above structure, since the luminaire main body 10a is equipped with the gas cleaning device 1, at least one lighting device is installed in each room. A wide range of gas cleaning can be densely performed through the device.

Further, the needle electrode 2 of the gas cleaning device 1 is negatively applied, and the dust collecting electrode body 3 a is integrally provided on the positive electrode part 4 and the positive electrode part 4 to which the positive electrode part 4 is positively applied. Between the needle electrode 2 and the dust collecting electrode body 3a, since the dust collecting electrode body 3a is detachably attached to the gas cleaning device 1. By making the electron flow and the ion flow generated in the same direction and making the electron-emitting side, which is the negative electrode, the needle-shaped electrode 2, the current density at the tip can be sufficiently increased, thus creating a stable and wide electric field region. Not only is it possible to collect dust, such as fine particles such as dust and odor, through the dust collecting electrode main body 3a without using a special dust collecting filter due to the stable and strong electric field range. And the dust collecting electrode body 3a is collected. Even if it is contaminated with dust, it is possible to instantly remove the dust collecting electrode body 3a from the gas cleaning device 1 to remove the dust collecting device, and attach it again to the gas cleaning device 1 for repeated use. .

Further, by enlarging the area of the positive electrode portion 4 facing the needle-shaped electrode 2 of the dust collecting electrode body 3a, the receiving area of the electron flow is widened and the electron rush density is lowered. A stable corona discharge will be maintained without causing an electron avalanche phenomenon.

Furthermore, since the dust collecting electrode body 3a that performs suction of electric wind and adsorption of fine particles such as dust and odor is positively applied, dust and odor that are influenced by electron flow The fine particles are more strongly adsorbed by the dust collecting electrode body 3a, and particularly the odor fine particles are a mixture of zeolite and pulp used in the dust collecting section 5, or activated carbon or dust containing the activated carbon. It can deodorize more strongly through the body's chemistry.

The dust collecting electrode body 3a of the dust collecting electrode 3 is surrounded by the positive electrode portion 4 which is positively applied and the positive electrode portion 4, and is mixed with zeolite and pulp to form the wavy penetration. An inner circumference of an electrode surrounding wall 10c, which is integrally joined with the dust collecting portion 5 in which the through hole 6 is formed to form a dust collecting electrode body 3a, and is erected so as to surround the needle electrode 2 It is removably housed in the electrode surrounding wall 10c via a peripheral surface convex portion 10d provided around the surface.

Reference numeral 13 denotes an upper portion of the cap body 10b so that the gas discharged through the through hole 6 of the dust collecting electrode body 3a is discharged from the cap body 10b located above the gas cleaning device 1. The gas discharge port formed in FIG.

The forehead equipped with the gas cleaning device in the present embodiment has the above-mentioned configuration. Next, the case where the forehead is used will be described.

First, as shown in FIG. 1, in the gas cleaning device 1 provided in the lighting device 10, the needle electrode 2 is applied negatively and the dust collecting electrode body 3a is applied positively. Since the positive electrode part 4 and the dust collecting part 5 formed by mixing zeolite and pulp having the positive electrode part 4 are integrally formed, the needle electrode 2 and the dust collecting electrode are formed. By making the electron flow and the ionic flow generated between the main body 3a and the main body 3a in the same direction and by using the needle-shaped electrode 2 on the electron emission side which is the negative electrode, the current density at the tip can be sufficiently increased, and thus stable and strong current can be obtained. Not only is it possible to create a wide electric field range, but the stable and strong electric field range enables the collection of dust, odor, and other fine particles such as fine particles without using a special dust collection filter. If dust can be collected through 3a Even when the dust collecting electrode body 3a is contaminated with the dust collecting material, the dust collecting electrode body 3a is instantly removed from the gas cleaning apparatus body 1a to remove the dust collecting material and the gas cleaning apparatus 1 again. Not only can it be attached to and used repeatedly, but it can also be disposable.

Further, by enlarging the area of the positive electrode portion 4 facing the needle-shaped electrode 2 of the dust collecting electrode body 3a, the acceptance area of the electron flow is increased and the electron rush density is lowered. A stable corona discharge will be maintained without causing an electron avalanche phenomenon.

Further, since the electrode body 3a for collecting dust, which attracts electric wind and adsorbs fine particles such as dust and odor, is positively applied, dust and odor, etc., which are affected by the electron flow The fine particles are more strongly adsorbed to the dust collecting electrode body 3a, and particularly the fine particles having an odor can be more strongly deodorized through the chemical nature of zeolite.

In the above embodiment, the needle-shaped electrode is erected on the negative electrode surface body to which a high voltage is negatively applied, and the negative electrode surface body is made of zeolite mainly containing silicic acid and aluminum oxide. At least one surface side of the formed dust collecting surface body is integrally provided, and the negative electrode surface body and the dust collecting surface body in the vicinity of the needle electrode are introduced with gas that penetrates each other. By forming a dust collection negative electrode by forming a through hole for water, it is possible to capture not only fine dust in the gas but also fine odor particles through the dust collecting surface made of zeolite. However, the material is not necessarily limited to zeolite, and may be formed of activated carbon or a dust collector containing the activated carbon, and may be a rubber-like or foam-like elastic body containing activated carbon. Carbon is contained in the elastic body However, the specific material, shape, thickness, location, quantity, etc. of the negatively applied needle electrode are not limited.

Further, in the above-mentioned embodiment, the dust collecting electrode is positioned at a predetermined distance from the needle electrode in advance so as to have the best electrolysis range with the needle electrode, and the dust collecting electrode is also arranged. The dust collecting electrode body of the dust electrode is integrally formed by the positive electrode portion positively applied and the dust collecting portion having the positive electrode portion, and the positive electrode portion and the dust collecting portion are respectively formed. They are alternately and integrally joined to each other so that they can be inserted into and removed from the electrode surrounding wall of the gas cleaning device, but the point is that they have to have the best electrolysis range with the needle electrode, and However, the dust collecting portion does not have to be formed by mixing zeolite and pulp, and may be formed by only one of zeolite or pulp, and is formed by activated carbon or a dust collector containing the activated carbon. And the dust collecting part contains activated carbon. Needless to say, it may be an elastic body having a foam or foam shape, and the presence or absence of carbon is not limited.

Further, the gas cleaning device is integrally provided in a lighting fixture main body of a lighting fixture formed in a substantially conical shape for locking a substantially rectangular cap body via a molding material such as synthetic resin, Moreover, the gas introduction hole and the gas discharge port are formed in the lower part of the lighting fixture main body and the shade, but it is not always necessary to have this configuration, and the gas introduction hole, the gas discharge port and the dust collecting electrode storage place are not required. The shape, quantity, formation location, etc. are by no means limited, and the gas purifier does not have to be integrally provided in the main body of the lighting fixture, and may be retrofittable to a commercially available lighting fixture, for example. Alternatively, the structure may be detachably mounted via a mounting means such as a screw. In the case of a lighting fixture that can be mounted on a ceiling, a wall, etc., the specific shape and size of the lighting fixture may be used. Say that size and weight are not limited in any way Needless to say, the type of ball used, such as a straight pipe, a round pipe, and a light bulb, does not matter.

[Effect of device]

 As described above, according to the present invention, since the main body of the luminaire is equipped with the gas cleaning device, at least one unit is installed in each room so that a wide range of gas cleaning can be performed densely through the luminaire. You can do it.

Further, a positive electrode portion to which the needle electrode of the gas cleaning device is negatively applied and the dust collecting electrode body is positively applied, and a dust collecting portion integrally provided on the positive electrode portion. Since the dust collecting electrode body is detachably attached to the gas cleaning device, the electron flow and the ion flow generated between the needle electrode and the dust collecting electrode body are in the same direction. However, by using a needle-shaped electrode on the electron emission side, which is the negative electrode, the current density at the tip can be sufficiently increased, so that not only a stable strong and wide electric field region can be created but also the stable strong Due to the wide electric field range, it is possible to collect dust such as fine particles such as dust and odor without using a special dust collecting filter, etc. through the dust collecting electrode body, and the dust collecting electrode. Even if the main body becomes dirty with dust, it will The electrode body can be detached from the gas purifying device to remove dusts and attached again to the gas purifying device for repeated use, or it can be disposable.

Further, by increasing the area of the positive electrode portion facing the needle-shaped electrode of the above-mentioned dust collecting electrode body, the area for accepting the electron flow is widened and the electron plunge density is lowered, whereby the electron avalanche phenomenon is generated. A stable corona discharge will be maintained without causing electric shock.

Further, since the main body of the dust collecting electrode, which performs the suction of electric wind and the adsorption of fine particles such as dust and odor, is positively applied, the amount of dust and odor affected by the electron flow is small. The particles are more strongly adsorbed to the dust collecting electrode body, and especially the odorous fine particles are the chemical properties of the mixture of zeolite and pulp used in the dust collecting part or the activated carbon or the dust collector containing the activated carbon. It is possible to deodorize more strongly via.

Therefore, the electron avalanche phenomenon does not occur at all, and the structure of the dust collecting electrode is not subject to any particular restriction. The dust collecting operation of the particles is highly stable and highly efficient, and the silence during gas cleaning is high. It is not only possible to maintain the above, but for example, an extremely excellent gas cleaning device that can densely clean a wider range of gas by equipping a lighting fixture with at least one unit installed in each room. It has come to have a special effect that it is possible to provide an illuminating device equipped with.
